摘要
为特种船舶的需要在AU螺旋桨基础上对叶型进行对称化处理得到对称螺旋桨模型,应用计算流体动力学方法为某AU型螺旋桨进行敞水数值模拟,得到该螺旋桨正向旋转时的水动力性能,并与实验图谱数据进行误差分析,证明数值方法的有效性。为对称螺旋桨进行了敞水性能模拟,对比数据分析对称螺旋桨水动力性能的优势和劣势,为特种船舶的推进设计提供可靠的参考数据。
This paper alters the blade section of AU propeller to build the symmetry propellers for a special boat,the open water hydrodynamics feature of AU propeller was simulated by CFD method.Research data were compared to the ex-periment chart and to verify the effectiveness of the numerical method.The force,torque,and related coefficient of both pro-pellers were compared.The merits and drawbacks of symmetry propeller were summarized through calculation and analyses.
